hi there, this is my code .Getting error 'list indices must be integers' please help. console shows B and none thanks

8. Part of Whole - get_class_average([alice]) should return a number ERROR

here:

results.append(get_average(students))

get_average() is only designed to handle a single student, students is a list with students, this is why you have a loop to get the individual student

here:

return average[results]

average() should be a function call, it calls the function you build earlier:

def average(numbers):
    
        total = sum(numbers)
        
        average = float(total) / len(numbers)
        return average
